Abstract (en)
[origin: US2004011618A1] Excellent durability and reliability are provided and assembling work is made easy. The clutch retainer 28a of the roller clutch 10a is prevented from being displaced in the axial direction. It is prevented that part of the clutch retainer 28a rubs the portion rotating together with the follower pulley 7a, so that the heat generation during over-run is prevented. Accordingly, grease degradation is prevented, and durability and reliability are improved. In addition, the inner clutch ring 21 of the roller clutch 10a and the rollers are provided with a chamfered portion along the outer periphery at the end thereof in the axial direction. Accordingly, the rollers 26 are positioned properly in the circumferential direction, while the inner clutch ring 21 is easily installed on the inner diameter side of the rollers 26, and the assembling work is made easy.
